Operating Modes and On-Chip Memory
Technical Data
BULKP — Bulk erase of EEPROM protect
Bit 6 — not implemented; always reads zero.
BPRT4 — Block protect bit for top 128 bytes of EEPROM (see below)
PTCON — Protect for CONFIG register
BPRT[4:0] — Block protect bits for EEPROM
Freescale Semiconductor, Inc.
Note that, in special modes, CONFIG may be written regardless of the
state of PTCON.
Each of these five bits protects a block of EEPROM against writing or
erasure, as follows:
For More Information On This Product,
1 = EEPROM cannot be bulk or row erased.
0 = EEPROM can be bulk erased normally.
1 = CONFIG register cannot be programmed or erased.
0 = CONFIG register can be programmed or erased normally.
1 = Protection is enabled for associated block; it cannot be
0 = Protection disabled for associated block.
